EVEN BETTERMarry all three of them Yuu!
My theory is that the dad had a secret crush on Yuu's mom, and that he is now trying to project Yuu as her "revival", he is not seeing Yuu for who he is.The dad is such an unlikeable piece of shit, not to mention a dumbfuck considering how poorly he analyzed Yuu's skills and his impact in his daugthers' lives.
Really hoping someone gets him off his high horse soon.
I think Yuu's mom had an affair with him and he is Yuu's dad. Notice how his father and the girl's mother is never mentioned.My theory is that the dad had a secret crush on Yuu's mom, and that he is now trying to project Yuu as her "revival", he is not seeing Yuu for who he is.
He is seeing his mother.
